Observations

• Deviations Observed are Likely Partially Due to
  The Class Allowing Continued Fairing of the Plug
  Prior to Each Mold Being Made.
• Deviations Observed are Likely Within the
  Technology Used to Reproduce Hulls and Plugs.
• Not All Etchells are the Same.
• Many Details Differ Between the Molds

Needed Future Actions

• Based on the Three Hull Scans and The Plug Scan
  The IGC Will Need to Determine What a Etchells
  Is?
• New Hull Drawings / Solids Will Have to be
  Generated
• Methods for Producing New Molds Will Have to be
  Standardized
• Plug Needs to Be Much Better Maintained
